I am using add_fields processor to add orchestrator.cluster.name

- add_fields:
          target: orchestrator.cluster
          fields:
            name: "test"

Note: it is a way we mention in our public doc - https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-module-kubernetes.html#_dashboard_32 for cases when cluster.name can't be detected automatically.

When testing (on kind cluster, where orchestrator.cluster.name can be defined) I've noticed that the field value is added to the existing field, but not get overwrite as claimed in doc and suppose to be in tests:
